Abstract: In one embodiment, a method includes receiving, from a beacon associated with a third-party content provider (e.g., a business), a current session information of the first user of an online social network. The first user's mobile device is proximate to and in a wireless communication session with the beacon, which is located at the third-party content provider. One or more second users who are associated with geographic locations within a threshold distance of the location of the beacon are selected. A notification referencing the selected second users is sent to the first user's mobile device, indicating that the second users are nearby.

Abstract: In one embodiment, a method includes sending, to an online social network, session information between a third-party content provider and a first user of the online social network. The session information includes information referencing an established wireless communication session between a first client system of the first user and a beacon of the third-party content provider. The beacon is physically proximate to the first client system at the time of the wireless communication session, and the wireless communication session allows the online social network to send social-networking information of the first user to the beacon. In response to sending the session information, a first set of social-networking information of the first user is received from the online social network via the beacon. The first set of social-networking information allows the third-party content provider to send, via the beacon, customized third-party content for display on the first client system.

Abstract: In one embodiment, a method includes receiving, from a beacon associated with a third-party content provider (e.g., a business), session information of the first user of an online social network. The first user's mobile device may be proximate to and in a wireless communication session with the beacon, which may be located at the third-party content provider. One or more second users, who are each connected to the first user in a social graph, may be selected. A communication session is not active between the beacon and the mobile devices of the second users. The selection may be based on selected second users being located within a predefined distance of the beacon (e.g., in the same neighborhood). A notification referencing selected second users (e.g., a prompt to invite the selected second users to the beacon location) may be sent to the first user's mobile device.

Abstract: In one embodiment, a method includes sending, via a beacon of a third-party content provider (e.g., a business), a request to associate with a user's mobile device. The request may be sent when the mobile device is proximate to the beacon, which may be located within a place of business. The request may include an attribute of the business (e.g., the type of business). A wireless communication session may be established between the beacon and the mobile device, and, in response, social-networking information of the user may be received, via the beacon. The particular information sent may be tailored to the business based on the received attribute, and a set of user-specified permissions may delimit what information is sent and to whom the information is sent. Third-party content may be customized based on the received social-networking information and sent to the mobile device for display.

Abstract: In one embodiment, a method includes receiving, from beacons of a third-party content provider (e.g., a business), session information for users of an online social network. A mobile device of each user may have been in at least one wireless communication session with at least one beacon, and during the session the mobile device was proximate to the at least one beacon. The session information may include an identifier for each of the users, which may be used to access social-networking information for each user. A report of business insights may be generated based on aggregated social-networking information (e.g., demographics) and aggregated session information (e.g., average duration of sessions) of the users. For example, the report may include statistics regarding the business' clientele. User-specified permissions may delimit which information may be included in the report. The report may be sent to a third-party system for display.
